Enterprise D easily! Last choice would probably be NX Enterprise as she was pretty much outgunned by everyone so I'd imagine it would be hard to relax.
1. D... The one I'd want to serve on if I did. 2. 1701... On one condition: my uniform's not red. 3. E... The Captain was less rational. Then it gets worse from here. 4. A... The ship had a short lifespan and problems to begin with. 5. B... Look at who the captain is. 6. C... Offal outcome, which is even worse than awful.
